New fuel for SPA...new engines have arived in SPA, tommorow decidion wether or not they will be used.

Looks like it's happening, and it seems Ferrari are responding to Honda's upgrade by bringing their own. With the same stipulations about introducing it this weekend.

Edit: He says whit fuel 20hp.

Seems rather a small bump for TJI. Is this just natural "lean it out and see what breaks" iteration?

Can someone explain to me how 20hp can come just from fuel? Not meaning to be naive, but 20 hp is a huge jump in this formula.

Ofcourse we dont know if it's 20 hp in peak mode , or 20hp average. I'm assuming if it's a fuel upgrade, then there would be an increase in horsepower for all engine settings.

Easy power even for a street car turbo setup. It all has to do with how good your combustion was before... and in the case of Honda it was not good.

The lithium polymer battery curve has been flat for some time with obvious limits. However,a group at MIT redesigned the oldest kind of lithium battery, the Lithium metal battery. They managed to make it safe, cool and rechargeable. It is much smaller than current lithium polymer batteries too. I can see this reborn lithium metal battery design making its way into F1 in two years.

Isn't the minimun volume set to be written on the 2018 technical rules?

If the volume and the weight is to same the same as today and is regulated.. you can work it either way.. make twice the number of cells for more redundancy.. or manage the cells to alternate and run cooler cells.. or use the same number of cells and design the centre of gravity better.

So the engine upgrade is worth 3-4 tenths, if it's worth that much by itself, it could mean 6-7 tenths ultimately once the upgrade is fleshed out and integrated properly with the chassis(aero tweaks to take advantage, better ERS recovery, less fuel saving). The extra 20hp could become less if they realize they can't run full power, then again it could be more, this is something you can only find out on track. Not to mention I don't think it's going to work flawlessly right away, that said I'd still introduce the upgrade now, no point in waiting.

Even?

I may have missed the point made in your post, but It is way easier to make power jumps with a street car, specially with a turbo one. Saab's have incredible figures with trionic management, with jumps of a minimum of 60hp with a simple click and no changes in the turbo layout, and 100hp jumps with minimal changes up to 400hp. Piece of cake.

But the way you do this with a street car has nothing to do with what you do in this formula: turbo cars are traditionally tuned down for a variety of reasons, from reliability to tax and marketing factors, so they run far away from their optimal mechanical setup.

The "easy" way to make more power with a road car is to ensure it can consume more fuel. Given that F1 is rate flow limited, that easy option isn't available.

Honda spends seven tokens on F1 upgrade for Belgian Grand Prix

A new compressor, ICE and new fuel to compliment.

It's a reasonable HP increase apparently (20hp talked about) but surely the big improvement will be efficiency.

More efficiency means less fuel saving and more powerful engine modes available for longer, ie race pace improvement.

[godlameroso]

So 3 for the combustion, 2 for the fuel system, 2 more for a new compressor?

Leaving 3 tokens for new ES and BMS?

That was my thinking as well. From what I've been able to gather Honda's vulnerability hasn't been raw power but efficiency. With Fernando and Jenson having to turn down the engines to save fuel for longer periods in the race than their rivals.

Less horsepower over the average race distance means you can't run as much downforce, the car becomes harder to drive, that's harder on the tires overall and it snowballs from there

More efficiency means more HP over the length of the race so a 20HP boost is just a bonus.
